Given that Son 8's mother is a carrier of the blindness allele

Assuming that the father is colorblind due to a genetic mutation, there are a few possible scenarios for how the son inherited the allele for colorblindness.

Genetic inheritance is the study of how certain inherited traits are passed down from generation to generation.

Assuming the father is colorblind due to a genetic mutation, there are a few possibilities for how the son inherited the colorblind allele:

Thus, in any of these scenarios, the son inherited the allele for colorblindness from one or both of his parents.

Explanation:

The Panama isthmus is indeed a patch of land which separates its sea from its Atlantic ocean to The pacific in two halves. The Panama Isthmus allows spreading the seafood applicable state, although due to geographical barrier, the very same turtle species were isolated. Its deep squirrels of liquid are diverged quite early as being against shallow water shrimps which are characterized by the rising of the Jamaica isthmus, first off the island can be crossed until it was closed through shallow water prawns and shallow-water animals. If Panama's black sea was established less than 1000 years, it has a greater effect on deepwater shrimp and very low water lobsters. Consequently, in water depth prawns, a disparity in hereditary degree (DNA) is higher than in shallow species. The deep waters have been affected earlier so the variation in DNA sequences throughout all sister species will not be the same.

Answer: Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle? ... Since not all organisms can utilize the nitrogen gas directly, these microorganisms convert nitrogen in different nitrogen compounds, such as ammonia, nitrites, and nitrates. In this article we explore how nitrogen is cycled and the important role of microbes in this cycle. ... Nitrogen is required by all living organisms for the synthesis of organic molecules such as amino acids, nucleic acids and proteins. The Earth's atmosphere contains almost 80% nitrogen gas

Bacteria play a central role:

Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.

Bacteria of decay, which convert decaying nitrogen waste to ammonia.

Nitrifying bacteria, which convert ammonia to nitrates/nitrites.

Denitrifying bacteria, which convert nitrates to nitrogen gas.

Explanation:

Answer: factors that limit a population size are limiting factors. Biotic potential is the amount of organisms that could be supported in an ecosystem if plenty of resources were available. Factors that cause a population to increase are 1)births: the number of births in a population in a certain period of time. 2) immigration: when organisms move INTO a population.

Explanation:

some examples of limiting factors are natural hazards, amount of food, amount/quality of water and air, predators deforestation.

The best clue that can be used to decide living thing or not a living thing is the observation of living or dead cells present in the specimen. All the living or dead organisms exhibit cells. Cell is a structural and functional unit of life. The growth and metabolism of living organism are dependent upon a cell. A cell in a life form exhibit organelles and components which are not found in non-living objects

The BEST clue you could use to decide: living thing or not a living thing- is option C. is it made of cells and

The living things have some basic characteristic features of life in them that help in determining if an object or thing is living or nonliving thing. these characteristic can be present in all or some, are as follows:
